Among them, after the construction of the building is completed, it is necessary to apply paint, install insulation materials, and lay floors. If the flatness of the building does not meet the requirements, hollowing is likely to occur and cause the paint, insulation materials and floors to fall off. Therefore, it is very important to detect the flatness of the building. The existing building flatness detection device needs to be moved to the side of the building wall and then adjust the direction when performing flatness detection on the building. It has the problems of large size and inconvenient operation; and the existing building flatness detection device has a small detection area, so the operation is cumbersome and it is difficult to quickly and comprehensively detect the walls of the building, which affects the detection efficiency.

The present invention detects and records the flatness of the building by setting a detection component. When the wall has a bulge, the lower marking rod marks the bulging area of ​​the wall; when the wall has a depression, the upper marking rod marks the depression area of ​​the wall, thereby realizing the flatness detection of the wall.

[0004] The disadvantages of the existing patent are: the existing building flatness detection device needs to be moved to the wall of the building and then adjust the direction when performing flatness detection on the building, which has the problems of large size and inconvenient operation; and the existing building flatness detection device has a small detection area, so the operation is cumbersome and it is difficult to perform rapid and comprehensive detection on the wall of the building, thus affecting the detection efficiency.

[0048] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a support portion is provided on the detection surface, and when the pull rope 6 is perpendicular to the axis of the drainage channel 2.2.1, the outer end of the marking rod 2.2 is flush with the support portion, and the drainage channel 2.2.1 is in a closed state. The detection rod is supported as a whole, so that the distance between the upper and lower ends of the detection rod and the wall is equal, avoiding detection errors caused by different distances between the multiple marking rods 2.2 on the execution rod 1 and the wall after being extended, ensuring that the extension lengths of the multiple marking rods 2.2 are equal and can improve the detection accuracy of the wall flatness.

[0049] The auxiliary rod 5 always moves along the axial direction of the drainage channel 2.2.1, and the valve plate 4 always moves along the radial direction of the drainage channel 2.2.1. The auxiliary rod 5 drives the valve plate 4 to open and close through the pull rope 6.

[0050] Specifically, Figure 7 , Figure 8 As shown, a receiving groove is provided on the inner wall of the drainage channel 2.2.1, and the valve plate 4 is located in the receiving groove, and the valve plate 4 closes the drainage channel 2.2.1 through a reset member 7. The receiving groove is used to accommodate the valve plate 4, and the valve plate 4 is slidingly sealed in the receiving groove. The valve plate 4 closes the drainage channel 2.2.1 through the reset member 7. In the present technical solution, the reset member 7 is a spring located between the receiving groove and the valve plate 4, and there are two valve plates 4. The two valve plates 4 are matched by the reset member 7 to close the drainage channel 2.2.1. At this time, the pull rope 6 is arranged perpendicular to the central axis of the drainage channel 2.2.1. The implementation method of the reset member 7 is not limited to the use of a spring, and it can also be other elastic elements, or the drainage channel 2.2.1 can be closed by magnetic attraction of the magnetic valve plate 4.

[0051] In order to prevent the marking rod 2.2 from spraying the marking liquid, a plugging piece 11 is provided in the port of the drainage channel 2.2.1 at the outer end of the marking rod 2.2. The plugging piece 11 prevents the marking liquid in the drainage channel 2.2.1 from being directly sprayed onto the construction surface to cause large-scale pollution. The plugging piece 11 is provided with micropores to allow the marking liquid to seep out slowly.

[0052] The specific structure of the liquid inlet component 3 in this embodiment is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the liquid inlet assembly 3 includes a liquid storage cylinder 3.1 and an elastic hose 3.2. The elastic hose 3.2 connects the liquid storage cylinder 3.1 and the liquid discharge channel 2.2.1. The liquid storage cylinder 3.1 is connected to the elastic hose 3.2 through a water pump 3.3. The liquid storage cylinder 3.1 can be set on the detection rod or on the support 9. The elastic hose 3.2 facilitates the telescopic setting of the detection rod. The elastic hose 3.2 passes through the sleeve 2.1 and is connected to the liquid discharge channel 2.2.1 of the marking rod 2.2.

[0053] The detection unit 2 can be fixed or driven by a driving device, which is specifically set according to actual needs and used in conjunction with the specifications of the support member 13. The sleeve 2.1 is slidably inserted into the detection surface, and a driving mechanism 12 is provided in the detection rod to drive the sleeve 2.1 to extend out of the detection surface. The driving mechanism 12 drives the sleeve 2.1 in the detection surface to extend out of the detection surface at the same time. The driving mechanism 12 includes a rotating shaft 12.1 set in the detection rod, a bevel gear 12.2 is provided on the rotating shaft 12.1, and a rack 12.3 meshing with the bevel gear 12.2 is provided on the outer wall of the sleeve. The rotating shaft 12.1 drives the rack 12.3 to move through the bevel gear 12.2, so that the sleeve slides and is inserted into the detection rod.

[0054] The specific implementation of this embodiment is as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown: Step 1: lift the detection rod in this embodiment by the handle 10 and place it on the construction surface to be detected. The handle 10 is easy to carry and easy to operate; stand the detection rod upright on the construction surface to be detected, and ensure that the support member 13 is in contact with the construction surface to be detected; Step 2: The marking rod 2.2 of the detection unit 2 is pressed against the construction surface to be detected. The detection unit 2 can be a fixed part matched with the support 13, or it can be moved outward toward the detection surface of the detection rod and pressed against the construction surface to be detected by the driving mechanism 12. Whether the detection unit 2 is fixed or sliding, the valve plate 4 is closed when the marking rod 2.2 and the support 13 are flush, that is, when the marking rod 2.2 is pressed against the construction surface to be detected and is flat, the valve plate 4 of the marking rod 2.2 is closed, the drainage channel 2.2.1 is closed, and the pull rope 6 is not subjected to force.

[0055] Step 3: Open the liquid inlet assembly 3, let liquid into the drainage channel 2.2.1 through the elastic hose 3.2, and mark the concave or convex construction surface to be inspected through the marking rod 2.2.

[0056] On the basis of the above steps, in order to increase the detection area, the mutually hinged actuator rods 1 in the detection rod can be rotated and opened so that each actuator rod 1 is in the same straight line to form a complete straight rod. The hinges of two adjacent actuator rods 1 can be connected by snapping to fix the actuator rods 1 in the unfolded state. The actuator rods 1 in the opened state can detect the flatness of the side wall of the wall at the same time, thereby increasing the detection area and effectively improving the detection efficiency.

[0057] Alternatively, the movable rod 1.2 on the actuator rod 1 is pulled out from the positioning rod 1.1. When the actuator rod 1 is in the folded state, the movable rod 1.2 is pulled out to ensure the horizontal detection area while increasing the vertical detection area. When the actuator rod 1 is in the open state, the movable rod 1.2 is pulled out to greatly increase the vertical detection area.

[0058] On the basis of the above, the inner wall of the positioning rod 1.1 that cooperates with the movable rod 1.2 is provided with a protruding clip distributed along the length direction of the positioning rod 1.1, and the movable rod 1.2 is provided with a slot that cooperates with the protrusion, and the slot is distributed along the length direction of the movable rod 1.2. The number of the protruding clips and the slots is multiple and equal, so that the movable rod 1.2 can stay in the set position during the process of being pulled away from the positioning rod 1.1.

[0059] Detection principle: like Figure 7 , Figure 8 As shown, when the marking rod 2.2 and the support member 13 are simultaneously in contact with the flat construction surface to be inspected, the elastic member 8 is in a compressed state, at which time the pull rope 6 is not subjected to force, and the valve plate 4 closes the drainage channel 2.2.1 under the action of the reset member 7; When the marking rod 2.2 detects that there is a protrusion on the construction surface to be inspected, the protrusion presses the marking rod 2.2 toward the sleeve 2.1. At this time, the pull rope 6 is pulled toward the sleeve 2.1 by the auxiliary rod 5. The valve plate 4 opens the drainage channel 2.2.1 under the action of the pull rope 6, so as to mark the protrusion; When the marking rod 2.2 detects a depression on the construction surface to be inspected, the depression causes the marking rod 2.2 to move toward the outside of the sleeve 2.1 under the action of the elastic member 8. At this time, the pull rope 6 is pulled toward the outside of the sleeve 2.1 by the auxiliary rod 5. The valve plate 4 opens the drainage channel 2.2.1 under the action of the pull rope 6, thereby marking the depression.

[0060] This embodiment has the following beneficial effects: the overall volume of the technical solution is small, and it does not need to occupy a large space. It is easy to lift the invention as a whole and place it at the place to be tested, so that it is easy to carry and easy to operate. The detection area is increased in the horizontal or vertical direction to make the detection rod more widely applicable, and the detection range is larger and the detection efficiency is higher, so that the staff can quickly find and repair uneven places, and the structure is simple and can adapt to a variety of different detection scenarios; the detection efficiency is greatly improved, and the construction surface to be tested can be quickly and comprehensively tested.

[0061] The specific embodiments described above are only preferred implementations of the present invention, and are not intended to limit the specific implementation scope of the present invention. All equivalent changes made according to the shape and structure of the present invention should be included in the protection scope of the present invention.
